windbg不会用，请大家指点

我修改了passthru，运行后dump，获得了dump文件后，用windbg分析，具体操作如下：
windbg是最新版本，下载的。symbol是service pack 2，从MSDN的光盘上来安装的。

打开windbg，设置symbol路径为C:\\WINNT\\Symbols;D:\\work\\sourcecode\\firewall\\0825\\passthru\\objchk\\i386;D:\\work\\sourcecode\\firewall\\0825\\passthru\\objchk\\i386\\PASSTHRU.pdb
其中第一个是系统symbol的安装路径，其余两个是我的passthru的路径。
source file路径设置如下：D:\\work\\sourcecode\\firewall\\0825\\passthru
image file路径设置如下：D:\\work\\sourcecode\\firewall\\0825\\passthru，

然后打开dump文件，却无法显示出错的源码，为什么？windbg的提示信息如下：
